APPARATUS FOR LASTING SHOES Original Filed July 6, 1934 2 Sheets-Sheet 2 in g Reissued Oct. 17, 1939 UNITED STATES PATENT OFFICE APPARATUS FOR LASTI NG SHOES Wayne E. Thompson, Winchester, Mass, assignor to Spray Engineering Company, Somerv1lle, Mass, a corporation of Massachusetts 20 Claims.

The present invention relates to machines which are used in the various processes for the cement lasting of shoes to apply an adhesive to shoe parts in order that they may be secured together in the lasting operation.

In my Patent No. 1,990,803, February 12, 1935, I have disclosed an improvement in the art of lasting shoes in which a modified form of the spray gun disclosed in my Patent No. 1,779,922, October 28, 1930, is utilized to advantage. As disclosed in said Patent No. 1,990,803 the work is stationary and the spray gun is held in the operatives hand so that the discharge nozzle of the spray gun may be transferred along the stationary work. Because of the reverse curves along the edge of the shoe bottom from the breast corner at one side of the shoe around the toe to the breast corner at the other side of the shoe, it is necessary for the operative to twist his wrist considerably during the transfer of the nozzle of the spray gun along or around the shoe bottom. Experience has demonstrated that this mode of operation is tiring.

The principal object of the present invention is to produce an apparatus, for use in practicing the method disclosed in said Patent No. 1,990,803, in which the Work is presented by both hands of the operative to relative stationary mechanism for delivering adhesive in the form of spray.

To the accomplishment of this object and such others as may hereinafter appear, the features of the present invention reside in certain devices, combinations, and arrangements of parts hereinafter described and then set forth broadly and in .detail in the appended claims, possessing advantages which will be apparent to those skilled in the art.

The various features of the present invention will be readily understood from an inspection of the accompanying drawings, illustrating the best form of the invention at present known to the inventor, in which Figure 1 is a view in elevation with certain parts cut away, showing a rear vieW of the spray gun mounted for operation and also showing the source of adhesive supply;

Fig. 2 is a view in left side elevation, partially in section, showing the construction of the spider base and showing the spray gun'in use for applying adhesive to an insole of a shoe assembled with an upper and a lining on a last;

Fig. 3 is a detail view in plan of the spray gun and of the parts associated immediately therewith;

Fig. 4 is a detail view in sectional elevation taken along the line 4-4 of Fig. 2, the spray gun not being shown; and

Fig. 5 is a view in sectional plan taken along the line 5'5 of Fig. 2.

Referring to the drawings, the illustrated embodiment of the present invention is provided with a dished spider base 1 (Figs. 1, 2 and 5) the free ends of the three legs of which are adapted to rest flat on the floor and are provided with screw or bolt apertures 8. The hub 9 of the base is provided with a vertical passage l (Fig. 2) in which an upstanding tube II is vertically movable. A set screw [2 (Figs. 1 and carried by the hub holds the tube in any desired position of elevation.

Referring to Fig. 4, upon the upper end of the tube N there is threaded a cap I3 surmounted by an upstanding lug 14 provided with an unthreaded opening 15. The shank of a stud [6 extends loosely through this opening, with the hexagonal head of the stud abutting one side of the lug Hi. Threaded upon the shank" of the stud t8 and abutting the opposite side of the lug i l is a gun support ll. With this construc tion the position of the gun support I! may be varied angularly with respect to the cap I3 and yet, by reason of the opening IE'being unthreaded', the support I1 and the head of the stud l 6 always abut the lug l4 so that the support is held firmly in place. Projecting forwar'dly'fr'o'm the sup port ll (Fig. 2) is an integral yoke IB'the arms of which (only one arm being shown) receive a thimble l9 threaded into a spray gun 20. Hexagonal locknuts'2 l threaded on the thimble, abut the top and bottom, respectively, of the yoke l8 and hold the spray gun in place. that the above named elements comprise, in effect, a stand upon which the spray gun 20 is adjustably mounted.

Preferably the spray gun Z0 is of the general type disclosed in Patent No. 1,779,922, issued October 28, 1930; More specifically the spray gun is identical with that disclosed in my Patent No. 1,990,803, above referred to, which is a modified form of the gun described and claimed in said Patent No. 1,779,922 and. is designed for use in applying an adhesive to shoe parts, thereby supplanting the brush formerly used to apply an adhesive to these parts in lasting operations. The spray gun 20 being identical in construction and mode of operation with that disclosed in my said Patent No. 1,990,803, it need not be described in detail here. It is sufficient to say that the characteristic comp-ressed air and coating material valve spindles 200 and 20 I respectively, (Fig.

It will be seen 3), which are arranged in planes normal to each other, are controlled from a thumb piece 22 (Figs. 1, 2 and 3) forming one end of an operating lever 23 at the side of the gun. The thumb piece 22, in addition to being arranged to be engaged and operated by the operatives thumb, is also arranged to abut an adjustable stop 24 threaded into the body of the gun for limiting the movement of the thumb piece. As explained more in detail in my Patent No. 1,779,922, there is a connection 262 between the lever 23 and the adhesive valve spindle 20| so that both the spindles 260 and 2|l| may be operated by the thumb of the operatives hand in its natural thumb closing movement.

Referring to Fig. 4 again, it Will be seen that the stud 6 has a passage 25 and that the support I! has a passage 26, larger than the passage 25 and aligned with it. These two passages are horizontal, and extending loosely through them is a spindle 21, the right hand end of which, viewing Figs. 1 and 4, is provided with spaced flanges 28 and 29, and the left hand end of which is provided with a reduced portion 3|] forming a shoulder 3|. Mounted loosely on the reduced portion 30 in engagement with the shoulder 3| is an arm 32 secured on the spindle by a nut 33 threaded to a reduced portion 34 extending from the reduced portion 30. The spindle 21 is maintained normally in the Fig. 4 position, that is, with the flange 28 abutting the head of the stud I6, by means of a spring 35 coiled about the spindle partially within the support passage 26 and interposed between the arm 32 and the end of the shank of the stud l6. The arm 32 has a length such that a boss 36 at one end thereof may be aligned with the thumb piece 22 of the spray gun as shown in Figs. 2 and 3.

In order to move the spindle 21 to the right, viewing Figs. 1 and 4, against the tension of the spring 35, and thus cause the boss 36 on the arm 32 to move the thumb piece 22 to operate the spray gun, the present invention contemplates connecting these elements with operating means which the operative may actuate independently of his hands. In the illustrated embodiment of the present invention the movement of the thumb piece 22 is controlled by the operatlves foot.

To this end the cap I3 is provided with a pair of ears 3'! (Figs. 1 and 4) between which is pivoted a bell crank lever 38 by means of a pin 39. Threaded into the upper arm 46 of the bell crank lever is a stud 4| provided with a knob 42 having cam surfaces interposed between and engaging the flanges 28 and 29 on the spindle 21. To the other arm 43 of the bell crank lever a clevis 44 is pivoted by means of a pin 45, and depending vertically from the clevis 44 is a link 46. With this construction it will be seen that a downward pull on the link 46 will cause the knob 42 to press against the flange 29 and so cause the spindle 21 and the arm 32 to move to the right, viewing Figs. 1 and 4. The boss 36 on the arm 32 is substantially engaged with the thumb piece 22 when the apparatus is not in operation, as shown in Fig. 1, and as a consequence any movement of the spindle 21 and the arm 32 to the right causes the boss 36 to move the thumb piece 22 and so operate the spray gun.

In order to pull the link 46 downwardly by foot power, the hub 9 of the base is provided at one side with an car 41, (Figs. 2 and from which depends a clevis 48. Pivoted to the clevis 48 by means of a pin 49 is one end of a lever 50, the opposite end of which is provided with a pedal 5|, (Fig. 5). Intermediate its ends the lever 50 is provided with an ear 52 to permit the formation of an opening 53 through which the end of the link 46 loosely passes. A nut 54 on the end of the link serves to hold the pedal 5| elevated from the floor.

The spring 35 is powerful enough to overcome the weight of the pedal lever 5|], the link 46, the bell crank lever 38 and the spindle 21 when no pressure is applied to the pedal 5| by the operative. Stated in another way the spray gun 26 is held out of operation and the pedal 5| is held normally raised by the spring 35, and when the operative releases his foot from the pedal after having pressed it down to move the spindle 21 to the right to operate the gun, the spring 35 draws the spindle to the left and raises the pedal 5| to throw the gun out of operation.

As is Well understood by those skilled in the art, in the use of spray guns employing a motive agent, the speed and amount of application of the coating material to the surface to be coated may be varied by the amount of opening movement of the motive agent and coating material valves within the gun. In the type of gun disclosed in Patent No. 1,779,922 and in the modification thereof disclosed in my Patent No. 1,990,803 referred to above, the amount of opening movement of the valves may be limited by a stop 24 (Fig. 2') which limits the amount of movement of the thumb piece 22. So long as the gun is held in the operatives hand, this type of stop is very effective because there is no strain on the gun when the thumb piece strikes the stop. In mounting the gun so that it may be operated by foot power, however, this type of stop is not desirable for the reason that foot movement is coarse as compared to the delicacy of movement of the thumb, and foot pressure is very great as compared to that ofiered by the thumb, and further, as compared to the minimum necessary to move the thumb piece. It is obvious, therefore, that the stop which limits the movements of the thumb piece 22 should not be on the gun, but should be elsewhere so that there is no strain on the gun when the pedal 5| is depressed.

To achieve this result the stop 24 is threaded into the gun as far as it will go so that the thumb piece 22 cannot strike it. The stop 24 is shown in this position in Fig. 4. As a substitute for the stop 24 the end of the arm 32 opposite the boss 36 is provided with an opening 55 (Fig. 4) through which is threaded a stud 56 provided with a knurled head 51. The threaded end of the stud 56 is reduced to form a pin 58 and a shoulder 59. Depending outwardly and rearwardly from the support I1 is an integral stop 60 (Figs. 1 and 4) provided with a narrow channel 6| which receives the pin 58. The stop 60 is aligned with the stud 56 so that when the arm 32 moves to the right, viewing Figs. 1 and 4, the shoulder 59 on the stud strikes the stop and thus limits the movement of the arm and therefore the movement of the boss 36 and the thumb piece 22. The stud 56 being threaded in the arm 32, it may be adjusted to vary the amount of movement of the spindle 21, and the stud is held in any desired adjustment by a lock nut 62. With this construction the force applied to the pedal 5| in excess of that necessary to move the thumb piece 22 is directed against the stop 60, and as this stop is an integral part of the support l1, none of this excess force is directed against the gun itself to subject it to strain as it is supported on the yoke I 8 (Fig. 2).

It will be observed that the pin 58 and the channel 6| play no part in the functioning of the stop 60. These elements function to maintain the boss 36 on the arm aligned with the thumb piece 22. As stated above, the arm 32 is held on the spindle 2'! by the nut 33, the spindle 21 is not thread-ed to the stud IE, and the support H- is threaded only to the stud l6 and not to the lug I4 on the cap l3. While this construction provides a convenient means of adjusting the angle of the spray gun 20, it will be seen that if the position of the support I1 is shifted slightly with respect to the cap l3, the arm 32 will not necessarily move with the support and the boss 36 may no longer be in alignment with the thumb piece 22. This result is prevented by the pin 58 and the channel 6! because any movement of the support ll relatively the support I! is provided with a thrust bearing comprising an arm 63 (Figs. 1, 3 and 4) upstanding integrally from the support and carrying a stud 64 threaded into engagement with the gun.

In the operation of the spray gun, motive agent under pressure is admited to the gun through a hose connection 65 extending from a source of supply (not shown) as is well understood. A liquid adhesive is admitted to the gun through a hose connection GBone end of which is mounted on a nipple extending from the thimble I9 secured to the gun. It will be apparent that the adhesive may be kept in any source of supply convenient for use with the present apparatus. It is preferred, however, to utilize the apparatus shown in Fig. l, for reasons which will presently appear.

This apparatus comprises a spider base 6'! and a tube E8 vertically movable thereon, constructed in a manner like that of the base I and the tube ll. Mounted for vertical movement on the tube 68, and provided with a set screw 69, is a hub it from which extends an integral arm 'H provided with a table i2 which supports a jar 13 containing the adhesive. To maintain the jar in position, the table is provided with three or more posts 14 (only two being shown) which may be provided with rubber covers substantially engaging the jar. Adapted to rest on the mouth of the jar is a cover 15 provided with a depending flange 16 adapted to fit loosely within the mouth of the jar. The cover is also provided with a central opening Tl, a vent I8, and upper and lower bosses "IQ and 80, respectively, through which the opening T! is formed. One end of a gooseneck BI is mounted in the boss 19 and the other end of the gooseneck receives the end of the hose connection (it. Depending from the lower boss into the jar E3 is a tube 82. With this construction, the flange it? serves to steady the cover F5 on the mouth of the jar and to guide and hold the tube 73 in proper position within the jar.

The adhesive contained in the jar T3 is prefv erably latex, and it is Well known that latex ooagulates readily upon exposure to the air. As the cap l5 and the tube 82 must be removed from the jar l3 when it is to be refilled, itis apparent that t e eX- may. coasu1a e in a film on the. interior of the tube so that when the tube is replaced in the jar 13 the film may be peeled off and drawn into the spray gun and upon the work in the form of pills.

To prevent this, the hub i0 is provided with an arm 83 on which is formed a cup 84. for holding a jar 85 of water. A bracket 86, interposed between the hub 10 and the arm 83, projects upwardly and is provided with a horizontal arm 81 positioned over the jar 85. The arm 81 serves 10 as a support for the cover 15 (indicated in construction lines) when it is removed from the jar T3 and is provided with a central opening 88 so that the tube 82 may extend into the water in the jar 85. In this manner the latex in the tube 82 is not exposed to. the air while the jar 73 is being refilled, and there is no opportunity for the lat-ex in the tube to coagulate and so clog the gun or possibly injure the work. It is appreciated that the latex in the tube 82 is exposed to the air while the tube is'being transferred from the jar 13 to the jar 85 and back again. Experience has, demonstrated, however, that this time interval is too short for the air to aifect the latex in the tube.

In operating the illustrated embodiment of the present invention the operative stands in the space at the back of the apparatus (Fig. 1). In this space the operative is out of the zone of the spray delivered to the work, that. is, the spray is delivered away from the operative. The stand for the gun is constructed to provide spaces at opposite sides of the spray gun out of the zone of spray so that the operative may extend his arms forwardly and hold the work in both hands to present the work in position to receive the spray delivered by the spray gun. The stand is sufficiently low to allow the operative to look over the spray gun downwardly upon the work. If the operative stands at the apparatus he operates the pedal 5! with the sole of his foot. If he is seated at the apparatus the pedal is operated with his heel. The set screw I2 permits the operative to adjust the height of the spray gun to suit his convenience, and to the same end the manner of mounting the support IT on the cap permits the adjustment of the spray gun angularly relatively to the cap 13.

In my said Patent No. 1,990,803 above referred to, I have described the use of the spray gun 20 in lasting operations where the gun is held in the operatives hand and the thumb piece 22 is operated by his thumb. When the gun is so held, the workbeing mounted upon a support, the operative slides the nozzle of the gun over or along the portions of the Work. to be coated. With the present invention, however, the gun is not moved at all, and the operative holds the work in his hands and moves it bodily with respect to the gun to transfer the portions ,to be coated into the path of discharge of the nozzle. The result achieved with the present invention is the same as that where the'gun is hung on the hand, so far as mere discharge of the coating material upon a surface is concerned, but the result is achieved in a much more eificient and speedy manner, and the spray is at all times discharged directly away from the operative.

As stated in my said Patent No. 1,990,803 the conical nozzle of the spray gun 26 is shaped as 7.0 it is so that the discharge orifice may be placed very near the work and so that if the marginal portions of the upper and its lining are not secured together before being assembled. one last, the .nozzle maybe. insertedbetween, the adjacent 7i i faces of these marginal portions to separate them. When the gun is hung on the hand there is no means of aiding the insertion of the nozzle between the marginal portions, with the result that if the upper and its lining tend to cling together, some difiiculty is experienced in separating them by means of the nozzle alone. With the present invention, however, the operative has both hands free to hold and manipulate the work, and as a consequence he may separate the marginal portions of the upper and its lining manually so that the discharge nozzle may be inserted between them with ease and in a minimum time.

To cause the discharge coating to be applied around or along the separated faces, the operative uses both his hands to move the work in the path of discharge of the nozzle, turning the work when necessary and easily holding it so positioned with respect to the nozzle so that the separated faces are provided with a uniform coating as desired. The coated faces of the marginal portions of the upper and its lining may be pressed together by the operatives hands after the coating operation has been completed and the separated faces withdrawn from the nozzle, or the operative may engage the insole with the nozzle and then slide the margin of the work towards the nozzle so that its discharge end is interposed between the marginal portions of the lining and the insole. In this position the coated face of the lining may be wiped into adherence with the adjacent coated face of the upper by drawing the Work along the discharge nozzle, at the same time exerting a slight downward pressure to press the lining against the upper as they move over the stationary nozzle. By the same mode of operation, the work may be moved and turned relatively to the discharge nozzle to effeet the application of coating to the exposed face of the marginal portion of the lining and to the marginal portion of the insole, after which the unit comprising the upper adhesively united to the lining may be overdrawn upon the marginal portion of the insole and secured thereto by the previously applied adhesive in any suitable one of the well known machines.

Since the operative, by using both hands to hold and move the work relatively to the stationary spray gun achieves the same coating effeet as when he manually moves the spray gun relatively to work mounted upon a support, it is not deemed necessary to describe in further detail here the position of the coating on the various shoe parts. This is fully described in my said Patent No. 1,990,803. However, in Fig. 2 I have shown an upper 89 secured to its lining 9B and assembled with an insole 9| upon a last 92. The work is held against the nozzle as shown so that it lies substantially fiat on the insole with its .dis-

: charge end 93 located at a point spaced from the of adhesive uniform in thickness and substantia1- ly uniform in width.
